REPEATING AIR-RIFLE.

Specification of Letters Patent.

Application illed November 10, 1918. Serial No. 800,108.

Patented Mar. 3, 1914.

To all whom t may concern Be it known that I, ARvInEoK, a subject of theKing of Sweden, and resident of St.. Louis, Missouri, have inventedcertain new and useful Improvements in Repeating Air- Ritles, of whichthe following is a specification containing a full, clear, and exactdescription, reference belng had to the accom- -panyng drawings, formlnga part hereof.

My invention relates to improvements in repeating air rifles, and theprimary object of my invention is to construct an air rifle comprisingan air pum with a valved chamber 'for the storagev o air, and to arrangemeans for bodily moving said chamber forl the operation of one of saidvalves to release the stored air; and a further object of my inventionis to construct an air rifle comprising a pump with a plurality ofvalved chambers'for the storage of air from said pump, 4and to arrangemeans whereby said chambers may be selectively broughtv to register withthe barrel of the rifle and to arrange a trigger for moving saidchambers for the release of the air in the selected chamber.

With the above purposes in view my invention consists in certain novelfeatures of const-ruction and arrangement of parts as will be.hereinafter more fully described, pointed out in the claims'andillustrated by the accompanying drawings, in which- Figure 1 shows inelevation a rifle constructed according to my invention, a portion oft-he cylinder and barrel and a portion of ythe stock being removed; Fig.2 is an enlarged transverse sectional elevation taken on the liucl 2-2of Fig. 1; Fig. 3 is a transverse sectional elevation taken through theplurality of air chambers; and Fig. 4 is a longitudinal, sectionalelevation taken on the v line 4-4 of Fig. 3, a portion of the cylinderand barrel beingshown.

Referring by numerals to the accompan ing drawings: 5 designates thestock, in t e forward upper margin of which there is a recess G and tothe rear of and in a plane beneath said recess is a recess 7, andextended vertically through the stock at a point immediately to the rearof the recess 7 is a trigger opening 8.. Formed vertically through thestock at about the longitudinal center of the recess 6 is a verticalbore 9.

10 designates a plate shaped to seat 1n each of the recesses 6 and 7 andarranged to be removably secured to the stock by means of a bolt 11.which yis fixed to the plate and arranged to be extended through theopen.- ing 0 in the stock and a knurled nut 12 arranged to be threadedto said bolt and engage the stock. Secured-to the plate 10 andprojecting forwardly beyond the end of said plateis a cylinder 13, andcarried by the cylinder is a barrel 14 which projects rearwardly beyondthe end of the cylinder 13. Fixed to said barrel are the usual sight andbead. Arranged for o eration in the cylinder 13 is a piston 15, s ownonly by dotted lines in Fig. 1. 'Secured to the piston 15 is a rod 16,the end of which projects beyond the forward end of the cylinder and hassecured thereto an operating knob 17. At the rear end of the cylinderthere is a head 18 and secured to said head and preferably by threadingis a `tubular shaft 19 which is in- :ternally'threaded at its free end.

20 designates a tubular sleeve arranged for rotation as well aslongitudinal Inovements upon the tubular shaft 19. At its rearmost endthe sleeve 20 is enlarged to receive the head of a tubular set screw 21which serves to limit the rearward movement of the sleeve 2O relative tothe tubular'.` shaft. Radiating from the sleeve 20 is a lplurality ofwebs 22 and connected withthe iouter ends of the webs is a cylinder 23and at the ends of the cylinder 23 are the heads 24 and 25. lprovided anumber of separate and distinct '-air chambers 26. In the head 25 thereare formed ports 27 communicating with each chamber and .formed in theouter face of the head 25 is a plurality of radiating channels 28leading from the sleeve 20 to nach port 27.

29 designates a cap plate for the head 25 which is -removably secured bymeans of screws 30. Formed in the head 24 in communication with each ofthe chambers 26 is a screw threadedopening arranged to receive athreaded sleeve 31, comprising a combined ball holder and tubular valvestem 32. Arranged to seat against the inner end of the threaded sleeve31 in each of the chambers 26 there is a disk valve 33, and arranged toseat in each port 27 there is a ball 34.

35 designates an extensile coil spring located in each chamber anddesigned to normally hold a ball such as 34 and a valve such as 33seated. Arranged to seat in the-rearmost endof the tubular set screw 21is a `ball 36 which is normally held seated by an extensile coil spring37. Carried by the plate 10 and preferably formed integral therewith Itwill thus be seen that there isis a pair of rearwardly extending perfo-vrated ears 38 in which is pivotally mounted a trigger 39.

entire cylinder forwardly which movement As shown 1n Fig. 2 the capplate 29 is provided. with a plurality of notches 40 each of which isarranged on a median line of each air chamber 26. Carried by the plate10 is a dog 4-ll which is spring actuated to normally engage vin saidnotches 40. By this means the valved, threaded tubular sleeve 31 in eachcylinder is brought to registration with the barrel 14.

, It will thus be seen that when the piston 15 is operated by amanipulation -of the knob 17 the air from the cylinder 13 will be forcedthrough the tubular shaft 19, will unseat the `ball 36, will passthrough each of the channels 38 and through each of the ports 27 intothe chambers 26, Where it will be stored and held by the valves 34 and33. A ball to be discharged is then inserted into one of the combinedball holders and tubular valve stems 32and, by reason of the in.- nertaper of said ball holder', the ball is frictionally held. The cylinder23 is then .rotated until the ball holder is brought to register withthe barrel, the dog 41 maintaining such registration. Thetrigger is thenmanipulated which, in its movement, bears against the cap plate 29 and-moves lthe first firmly seats the end of the barrel 14 into thethreaded tubular sleeve 31 until 'the end of the barrel engages the ballholder. A continued movement of the trigger ,causes further longitudinalmovement of the ent-ire cylinder which means that the barrel moves theball holder in a position to unseat the valve 33, thus-.releasing theair from. the chamber 26 and driving out the ball from the ball holder.

s It is obvious that all of the chambers are simultaneously filled ywithcompressed' air and that, if it be desired to use the rifle as arepeating rifle, it is only'necessary to supply a ball toeach ballholder. v.

I claim:

1. An air rifle, comprising a barrel, avalved air chamber, and means forbodily moving the air chamber to effect a release of the air therein todischarge through said barrel.

2. An airrifle, comprising a barrel, a plurality of valved air chambersarranged to communicate one at a time with s/aid barrel, and means foreffecting a release of the air stored in the chamber in communicationwith the barrel.

3. In an air rifle, an air compressing means, a revoluble unitcomprising a plurality of air chambers, means for selectivelyvbringingany one of said chambers into communication with saidlbarrel, and meansfor releasing the air from said selected chamber to discharge throughsaid barrel.

.4,'In an air riie, a piston, a cylinder, a tubular shaft supported bysaid cylinder, a unit comprising a number of. valved air chambersrotatably mounted on' said shaft, a ball holder in communication witheach chamber, a barrel, means for selectively holding any one of saidball holders in parallelism with said barrel, and a trigger for bodilyvmoving said unit to bring said ball holder to enga-ge with said'ba-rrelto effect a release of the air fromsaid selected chamber to dischargethrough said barrel.

In testimony whereof, I have signed my name to this specific-ation, inpresence of two subscribing Witnesses.
